Too much rain can cause your pool water to rise to level which can cause MAJOR problems. As the water rises to the top of the tile and reaches the bottom side of the deck, the water will begin to drain between the top of the tile/pool and the deck. As it finds it way over under the deck, it will then drain down the back side of the pool's shell. The water will erode the soil which is supporting the entire pool. In a worst case scenario, the water can erode enough soil and the pool loose enough support that the entire pool moves, cracks, and even snaps re-bar under the weight of thousands of gallons of pool water.
If your pool has a sand or DE filter, you should backwash your pool until you have drained enough water. The proper water level should be so the mouth of the skimmer is half full or about 3 inches from the bottom of the skimmer. Do not drain too much water out of your pool or the pump will begin to suck air and can burn out. If you have a cartridge filter (no backwash system), you need to call Blue Cactus Pool Service LLC who will bring out a portable pump to lower the water level. Again, too much water in your pool can literally ruin your entire pool costing tens of thousands of dollars to repair. Call Blue Cactus Pool Service LLC as soon as possible. 623-889-1366
